Surfaces and Partial Derivatives;
Tangent plane and error estimation

A series of free Calculus 2 Video Lessons from UNSW - University of New South Wales, Sydney.

Lec1: Surfaces and Partial Derivatives
Lecture on the mathematics of surfaces and partial derivatives. Levels curves are discussed and how to use them to sketch surfaces of functions. Many examples are discussed on how to calculate partial derivatives. Such ideas are seen in university mathematics.

Partial derivatives and PDEs tutorial
This is basic tutorial on how to calculate partial derivatives. The ideas are applied to show that certain functions satisfy a famous partial differential equation, known as the wave equation. Such ideas are seen in university mathematics.

Lec2: Tangent plane and error estimation.
Lecture on the mathematics of tangent planes and error estimation. Plenty of examples are presented and solved. Such ideas are used in university mathematics.

Partial derivatives and error estimation
I explain the calculus of error estimation with partial derivatives via a simple example. Such ideas are seen in university mathematics.
